DEPTH-GAGE.

Specification of Letters Patent.

Patented May 16, 1916.

Application flied epm 17, 1915. serial No. 22,043.

To all whom t may concern:

Be it known that I, CLARENCE B. LAMBER- soN, a citizen of the United States, residing at I/Vilkinsburg, in the county of Allegheny and State of Pennsylvania, haveV invented certain new and useful Improvements in Depth-Gages, of Vwhich the following is a specification.

My invention relates to improvements in depth gages.

An important object of the invention is to provide means of the above mentioned character, which are extremely simple in construction, inexpensive to manufacture, and convenient in use.

A further object of the invention is to provide a novel and simple resilient clip adapted to be detachably mounted upon a scale-blade, and to adjustably hold a rod or bar.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same, Figure 1 is a side elevation of a tool embodying my invention, Fig. 2 is an'edge elevation of the same, Fig. 3 is a transverse sectional view taken on line 3 3 of Fig. 1, and, Fig. 4 is a perspective view of a resilient clip.

In the drawings, wherein for the purpose of illustration is -shown a preferred embodiment of my invention, the numeral 5 designates a scale-blade, having a scale or scales 6 formed thereon. The'scale or scales may be in any suitable graduations.

The numeral 7 designates a rod or bar, of the same length as the scale blade 5 and longitudinally adjustably mounted upon the scale-blade 5, with one end thereof adapted to enter a groove 8, the depth of which is to be ascertained.

The invention embodies a spring clip designated as a whole by the numeral 9, and formed of a section of resilient wire or the like. This section of wire is bent into the form of a Ueshaped main body portion 10, having transverse portions 1l. Atthe ends of these transverse portions, the section of wire is bent to form relatively large eyes or ,..loops 12, arranged at a right angle to the body portion 10. The ends of these loops are extended in the form of small loops or Ushaped portions 13, arranged at a right angle to the loops 12, and parallel with the body portion 10, as shown. At their free ends the loops 13 carry upwardly extending resilient holding fingers 14, the upper ends of which are preferably slightly hooked or curved, as shown at 15.

In use, the clip 9 is arranged upon one edge of the scale-blade 5, the body portion 10 being disposed upon one side thereof and the small loops 13 engaging their opposite side, whereby the clip as a whole is securely and yieldingly held in place upon the scale,- blade. The rod or bar 7 is then passed longitudinally through the large loops 12 but does not engage therewith, said rod engaging the inner sides of the curved ends 15 of Vthe resilient ngers 14, and held thereby in proper frictional engagement with the side of the scale-blade 5. The rod 7 may now be moved longitudinally with relation to the scale-blade, so that one end thereof enters the groove 8 to engage with its bottom, the opposite end of the rod indicating upon the scale 6 the depth of the groove. The resilient ngers 14 properly hold the rod 7 against accidental movement, but permit of its convenient adjustment, when desired.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be' resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having vthus described the invention, I claim 1. A device to hold a 'rod upon a scale blade, comprising a resilient clamp having portions adapted to be arranged upon opposite sides of the scale blade, and a resilient nger carried by one portion and having a recess for receiving the rod and holding it in contact with the scale blade.4

2. The combination with a blade provided with a scale, of a rod to be moved longitudinally thereof, and a resilient spring clip embodying yielding members to engage with opposite sides of the blade and resilient fingers to engage with the rod.

3. A spring clip to adjustably hold a rod upon a scale-blade, formed of a section of resilient wire bent to provide an approximately U-shaped main body portion to be arranged upon one side of the scale-blade with main loops carried by the ends of the body portion and having loops at their free ends to engage with the opposite side oi the scale-blade, and resilient ingers carried by the second named loops to engage with the rod. y

1. A device of the character described, comprising a pair of resilient clamps formed of wire and having oppositely arranged portions adapted to engage with opposite sides of the scale blade, means for connecting the clamps, and resilient fingers carried by Vportions of the clamps and having recesses to receive the rod and hold it in contact With the scale blade.

Gopiel of this patent may be obtained for 5. The'combination with a blade provided with a scale, of a rod to be moved longitudi- Y nally thereof, a `resilient spring clip embodying yielding members to engage With opposite sides of the blade, and means carried by the clip for holdingthe rod inadjust'ed position relative to the blade.

. In testimony whereof I aiiix my signature i five cents each, by addressing the "Commissioner of Patents. Washington, D. 0."
